My Slow Cooker Takes Too Long

I like using my slow cooker, but it takes way too long to cook stuff. Some
foods take 6 - 8 hours. Can you imagine such a thing?
I wonder if I should hook it up to a 240 circuit. That should cut the
cooking time in half.

As usual, the village idiot has once again demonstrated his
incompetence.
Mark has it right. With a resistance load, doubling the voltage
increases the
power (watts) by 4. That is because of the simple fact that doubling
the
voltage also doubles the current. 2 x 2 = 4.
Got it now harry, or as usual, do you want to argue on and further
make an ass of yourself?

Your all wrong. The element will heat increasing resistance. Power will be
less than 4 times. My cooker will start to boil liquid around the sides
after a while. I don't think there is a thermostat. I'm guessing the low
uses a series diode.

That's true if you want to get into second order effects. But this
isn't
a light bulb filament. It's a heating element in direct contact with
water,
so the temp of the element probably isn't going to change
dramatically. For example, for heating elements for spas
and hot tubs, the rated power is given as 4X when going
from 120V to 240V. The one in my spa is rated at 1500W
at 120V, 6000W at 240V. With the cooker you'd see some
increase in resistance and it wouldn't be exactly 4X, but it
would be in the ballpark.

My cooker has a removable ceramic pot. There is air between the pot and
inner metal wall, and the heater is on the inside. For the pot to get to
boiling, the air must be a lot hotter. I could try measuring it, but
probably not.

Pedantic response -
The cooker would produce about 4x the heat (briefly, before it burned out).
As Frank notes, the heat may boil out the water, which does not improve
the cooked product.
In any case, cooking rate, like other chemical reactions, in general
approximately doubles for every 10 degrees C temperature rise.

That's nothing, I have a fast cooker that cooks too fast. I wonder if I
hooked it to a couple of flashlight batteries if that would slow it
down? It's hell when you try to cook something and it cooks before you
can get a plate from the cabinet. o_O

I can't get the spirits and ghosts out of my medium cooker. It keeps
moaning, and asking why I killed it, and calling for "Rosabelle believe".
Which seems to be a magic code.
